Over the past decade, Bluetooth has become almost the default way for billions of devices to exchange data over short distances, allowing PCs and tablets to transfer audio to speakers and phones to zap pictures to nearby computers. Now, researchers have devised an attack that uses the wireless technology to hack a wide range of devices, including those running Android, Linux, and, until a patch became available in July, Windows.
BlueBorne, as the researchers have dubbed their attack, is notable for its unusual reach and effectiveness. Virtually any Android, Linux, or Windows device that hasn’t been recently patched and has Bluetooth turned on can be compromised by an attacking device within 32 feet.
